Running Classic 5 5.0.422.0-d
Geogebra crashes (exits, no error msg shown) when displaying a function
such as : sqrt(x^2-4x+3)-x
One sees the graphics being constructed when entering the function (o how I hate this) then just before pressing enter, all that remains is 3 points (what is this new feature that shows spurious points in the graph ???) and when enter is pressed, bingo, Geogebra vanishes.
This does happen quite frequently, but not all the time; should be however easy to reproduce.
The same question 
Please update to the latest version.
